: A goldmine for power supply enthusiasts. While the linked video covers a different DIY module, searching their forum for "Wan Nien" often yields high-res photos and community-traced diagrams. BadCaps.net The Wan Nien 101V0 (often labeled with the

Forums: Check enthusiast sites like BadCaps.net or Samy's Arcade Repair. Users often upload hand-drawn diagrams or high-resolution photos of the trace side of the board. Regulation: The feedback loop is almost always handled

4. Secondary Side (Rectification & Regulation)

• Regulation: The feedback loop is almost always handled by a standard TL431 adjustable shunt regulator and an optocoupler (e.g., PC817). This is a proven, reliable standard.
• Output Filtering: The schematic usually shows minimal electrolytic capacitors on the output rails.
